Description

Technical Field

[0001] This utility model relates to the field of electronic product accessories, and in particular to a clamping structure and a power tool. Background Technology

[0002] Handheld power tools are a common type of power tool. Most current handheld power tools are powered by battery packs. The battery pack is clamped and fixed to the bottom of the power tool by a clip, thereby providing power to various electrical components inside the tool. The structure of the battery pack currently used is shown in patent publication CN117317488A. This structure shows that the top of the battery pack is provided with an elastic protrusion. The battery pack is engaged with the clip of the power tool through the elastic protrusion at the top, thereby clamping and fixing the battery pack to the tool housing. This method of using only one side of the battery pack and the tool housing to engage results in relatively poor engagement stability, which is not conducive to the stable operation of the power tool. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes a clamping structure.

[0004] The technical solution adopted by this utility model is as follows:

[0005] A clamping structure includes a first outer shell and a second outer shell. The first outer shell has a slot, and the bottom of the slot has an engagement step. The slot wall has two engagement openings, which are located on the same straight line. The second outer shell has a push plate slidably disposed thereon. The push plate has a protrusion and two engagement rods slidably disposed thereon. The two engagement rods are located on the same straight line and engage with the two engagement openings respectively. The protrusion engages with the engagement step.

[0006] In this clamping structure, a battery pack is located inside the second outer shell. The second outer shell plus the battery pack constitutes a battery pack. The second outer shell is inserted into a slot in the first outer shell. The protrusion on the second outer shell engages with the engaging step, and the engaging rod on the second outer shell engages with the engaging opening, thereby achieving a secure engagement. This clamping structure features a protrusion engaging with the engaging step and three engaging rods engaging with the engaging opening, thus achieving triple engagement. This triple engagement provides greater stability and prevents the first and second outer shells from easily disengaging.

[0007] In summary, this clamping structure achieves triple engagement by using the protrusion to engage with the engagement step and the engagement rod to engage with the engagement port. The triple engagement is more stable, and the first outer shell and the second outer shell are less likely to disengage.

[0008] Optionally, it also includes a first reset spring, which is disposed inside the second housing, with one end of the first reset spring abutting against the inner wall of the second housing and the other end of the first reset spring abutting against the push plate.

[0009] In this clamping structure, when the engaging rod engages with the engaging port and the protrusion engages with the engaging step, a stable engagement is achieved. When it is necessary for the first housing to disengage from the second housing, the pusher on the first housing can be pushed to disengage the engagement. After the external force is removed, the pusher returns to its original position under the action of the first return spring.

[0010] Optionally, a second return spring is also included, which is disposed between the two locking rods, with its two ends respectively abutting against the two locking rods.

[0011] The second return spring has a tendency to spring the two springs apart. The function of the second return spring is to achieve the elastic installation of the two locking rods.

[0012] Optionally, the push plate has an installation through hole, and the locking rod is provided with a limiting piece, which is clamped in the installation through hole.

[0013] Optionally, the limiting piece is an L-shaped limiting piece.

[0014] The limiting plates are designed to mate with the mounting through holes to improve the installation stability of the engaging rods on the push plate. Simultaneously, to ensure stable installation between the two engaging rods, the two ends of the second return spring abut against the limiting plates on the two engaging rods. The two L-shaped limiting plates form a protective cavity, within which the second return spring is located.

[0015] Optionally, the engaging step is a triangular engaging step, and the protrusion is a triangular protrusion.

[0016] Optionally, the engaging rod has a triangular contact surface, which is used to contact the engaging port.

[0017] The triangular contact surface facilitates the smooth sliding of the locking lever out of the locking slot when disengaging.

[0018] Optionally, the second housing has a first through hole and a second through hole, the protrusion of the pusher is located in the second through hole, and the contact end of the pusher is located in the first through hole.

[0019] An electric tool, further comprising the clamping structure described above.

[0020] The beneficial effects of this utility model are: by using the protrusion to engage with the engagement step and the engagement rod to engage with the engagement port, a triple engagement is achieved, which is more stable and makes it less likely for the first shell and the second shell to detach from each other.

[0032] In this clamping structure, the second outer shell 2 contains a battery pack. The second outer shell 2 plus the battery pack constitutes a battery pack. The second outer shell 2 is inserted into the slot 101 of the first outer shell 1. The protrusion 302 on the second outer shell 2 engages with the engaging step 1011, and the engaging rod 4 on the second outer shell 2 engages with the engaging opening 1012, thereby achieving a locking and fixing. In this clamping structure, the protrusion 302 engages with the engaging step 1011, and the engaging rod 4 engages with the engaging opening 1012. Furthermore, there are three engaging rods 4, thus achieving triple locking. This triple locking is more stable, and the first outer shell 1 and the second outer shell 2 are less likely to disengage.

[0033] In summary, this clamping structure achieves triple engagement by using the protrusion 302 to engage with the engagement step 1011 and the engagement rod 4 to engage with the engagement port 1012.

[0035] In this clamping structure, when the engaging rod 4 engages with the engaging port 1012 and the protrusion 302 engages with the engaging step 1011, a stable engagement is achieved. When it is necessary for the first outer shell 1 and the second outer shell 2 to disengage, the pusher 3 on the first outer shell 1 can be pushed to disengage. After the external force is removed, the pusher 3 returns to its original position under the action of the first return spring.

[0036] As attached Figure 1 ~Appendix Figure 4 As shown, it also includes a second return spring 6, which is disposed between the two locking rods 4, with both ends of the second return spring 6 abutting against the two locking rods 4 respectively.

[0037] The second return spring 6 has a tendency to spring the two springs apart. The function of the second return spring 6 is to achieve the elastic installation of the two locking rods 4.

[0038] As attached Figure 1 ~Appendix Figure 4 As shown, the push plate 3 has an installation through hole 303, and the locking rod 4 is provided with a limiting piece 5, which is clamped in the installation through hole 303.

[0039] As attached Figure 1 ~Appendix Figure 4 As shown, the limiting piece 5 is an L-shaped limiting piece 5.

[0040] The limiting piece 5 is designed to engage with the mounting through hole 303 to improve the installation stability of the engaging rod 4 on the push piece 3. Simultaneously, to ensure stable installation between the two engaging rods 4, the two ends of the second return spring 6 abut against the limiting pieces 5 on the two engaging rods 4 respectively. The two L-shaped limiting pieces 5 form a protective cavity, within which the second return spring 6 is located.

[0041] As attached Figure 1 ~Appendix Figure 4 As shown, the engaging step 1011 is triangular, and the protrusion 302 is triangular.

[0042] As attached Figure 1 ~Appendix Figure 4 As shown, a triangular contact surface 401 is provided on the locking rod 4, which is used to contact the locking opening 1012.

[0043] The triangular contact surface 401 facilitates the smooth sliding of the engaging rod 4 out of the engaging slot 1012 when disengaging.

[0044] As attached Figure 1 ~Appendix Figure 4 As shown, the second outer shell 2 has a first through hole 201 and a second through hole 202. The protrusion 302 of the pusher 3 is located in the second through hole 202, and the contact end 301 of the pusher 3 is located in the first through hole 201.
